MAX SCHMIDT, OF HIRSCHBERG, GERMANY.

CYLINDER FOR STEAM-ENGINES AND THE LIKE.

Specification of Letters Patent.

Patented July 29, 1913.

Application filed September 23, 1912. Serial No. 721,839.

To all whom it may concern:

Be it known that I, MAX SCHMIDT, director, a citizen of the Kingdom ofPrussia, Empire of Germany, residing at I-Iirschberg. Province ofSilesia, Germany, have invented certain new and useful Improvements inCylinders for Steam-Engines and the Like, of which the following is aspecification.

My invention relates to improvements in cylinders for steam engines andthe like. And the object of the improvements is to provide a cylinder inwhich the admission valve for the steam or other pressure fluid isdisposed within the cylinder head, the latter being constructed in theform of a valve casing. V

For the purpose of describing the invention an example embodying thesame has been shown in the accompanying drawing, in which a longitudinalsection of the cylinder head equipped with the admission valve is shown.

Referring to the example illustrated in the drawing, the cylinder head ais made hollow and it is formed with an inlet passage (Z and an outletpassage 6. The inlet passage is connected with a suitable admission pipe(not shown) and the outlet passage communicates with the steam chest.The-cylinder head is provided internally with a partition f which isformed with a valve seat 9. On the latter an admission valve 5 is seatedwhich is adapted to be operated by means of a hand wheel 0 mounted onthe valve stem it.

By the construction described the cylinder head is heated by the steamor other pressure fluid which passes through the said head, and suchheating is particularly effective, by reason of the whirls produced bythe steam passing through the valve. A further advantage of my improvedconstruc-' tion resides in the fact, that a special valve casing isavoided. Thereby the cost of con struction of the engine is reduced, andthe engine requires less space. The admission of the pressure fluid tothe opposite end of the cylinder may be made in any preferred way.

I claim herein as my invention:

In a cylinder for steam engines and the like, the combination with thecylinder, of a hollowcylinder head provided with admission and outletpassages for the pressure fluid and constructed internally in the formof a valve chamber, and an admission valve disposed within said cylinderhead and equipped with operating means.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

MAX SCHMIDT.
